NOTE:
Use J 36850 or equivalent during assembly in order to retain checkballs or to lubricate components. Lubricants other than the recommended assembly lube changes the transmission fluid characteristics and causes undesirable shift conditions or filter clogging.
IMPORTANT:
After cleaning the transmission case, allow the case to air dry. Do not use cloth or paper towels in order to dry the transmission case or any other transmission components. Lint from the towels can cause component failure.
